UBT2A331MHD

The UBT2A331MHD is a radial-lead aluminum electrolytic capacitor rated at 330 µF and 100 V, designed for high-temperature operation and robust performance. It combines a compact φ16 × 30.5 mm can package with radial leads (7.5 mm spacing) for through-hole mounting in demanding electronic systems.

Targeted use cases include automotive and industrial electronics where high temperature endurance, reliable ripple handling, and stable capacitance are required. Key value drivers are a wide operating temperature range (−40 °C to +125 °C), AEC-Q200 qualification, and endurance specified for long life at elevated temperature.

Key Features

• Electrical Performance — 330 µF capacitance at 100 V rated voltage with ±20% tolerance for bulk energy storage and smoothing in DC circuits.
• Low Loss — tanδ 0.08 (max.) at 20 °C and 120 Hz for the 100 V rating, supporting efficient AC ripple handling and reduced heating under AC stress.
• Leakage Current — Specified leakage current of 990 µA, measured per the product definition, enabling predictable bias behavior in power circuits.
• Ripple Current Capability — Rated ripple current of 1.199 A at 120 Hz and 1.79 A at 100 kHz to support decoupling and smoothing under AC ripple loading.
• High-Temperature Endurance — 5000 hours life/ endurance at +125 °C (per part/endurance category), providing long-term performance in hot environments.
• Thermal Range — Operating from −40 °C to +125 °C to cover wide ambient conditions and elevated internal case temperatures.
• Mechanical & Packaging — Radial can package, lead spacing 7.5 mm, physical size φ16 × 30.5 mm; supplied in bulk (no terminal forming) / bag packing for production handling.
• Quality & Compliance — AEC-Q200 qualified and RoHS compliant, meeting requirements for regulated electronics manufacturing and high-reliability applications.

Typical Applications

• Automotive Electronics — Suitable for vehicle electronic control modules and power systems that require AEC-Q200-qualified capacitors with extended high-temperature endurance.
• Power Supply Filtering — Bulk energy storage and smoothing for DC power rails where 100 V rating and 330 µF capacitance address ripple and transient demands.
• Industrial Control — High-temperature industrial assemblies and control equipment that need capacitors rated for long life at +125 °C.

Unique Advantages

• High-Temperature Endurance: 5000 hours rated life at +125 °C supports designs requiring sustained high-temperature reliability.
• AEC-Q200 Qualification: Explicit AEC-Q200 rating supports selection for automotive and other high-reliability programs.
• Predictable AC Performance: Low tanδ (0.08 at 120 Hz, 20 °C) and specified ripple currents enable controlled heating and stable operation under ripple stress.
• Compact Through-Hole Form Factor: φ16 × 30.5 mm radial can with 7.5 mm lead spacing balances board footprint and required capacitance for power applications.
• Regulatory Compliance: RoHS compliant to align with environmental requirements for electronic assemblies.
• Production-Friendly Packaging: Bulk (no terminal forming) / bag packing simplifies handling for automated or manual assembly workflows.
